MEDI CHECK Speicheltest: can a microbiome test help?

A saliva-based microbiome test like MEDI CHECK can provide a snapshot of your gut bacteria composition, but its clinical utility remains limited. While the microbiome is linked to metabolism, immunity, and even mood, current evidence does not support using such tests for diagnosis or personalized treatment in most healthy individuals. Many commercial tests overstate the significance of specific bacterial strains or offer costly personalized diets without robust validation. The test may reveal general patterns such as low diversity or imbalances in certain genera, which can be addressed with broad dietary improvements (e.g., more fiber, fermented foods). However, without accompanying symptoms or medical context, the results are not actionable. The evidence is mixed: mechanistic and observational studies exist, but no clear clinical guidelines endorse routine microbiome testing for health optimization. Safety note: Do not make drastic dietary or supplement changes based solely on test results; consult a healthcare professional if you have specific concerns.
